آخر and آخه show interrogatory anger. They are related to Arabic آخر (end). It somehow means "overall" or "in conclusion".
آخر normally means "end" . Both of them pronounced like آخر in Arabic meaning "other" (with fat-he).
The other آخs are just sounds:
آخ and اوخ are sound of pain (ouch!)
اخ [æx] is sound of disgust (aargh!)
آخی [axei] is sound of showing emotion or grief.
آخیش [axeiʃ ] is sound of relief.
